VC++ 屏幕画笔，可在窗体上写字的小程序，像一支电子笔一样在窗口的任意处划线或写字，可以直接在屏幕上作图。开发这个软件的目的是为了方便教学。你可以直接在屏幕上进行圈点。由于本软件提供了不少热键，所以使用起来会很方便的。启动画图时自动隐藏主程序，还可以设置是否是在最前端显示、设置画线颜色、画笔风格、启动时自动开始等.

A new grid load frequency control approach is proposed for the doubly fed induction generator based wind power plants. The load frequency control issue in a power system is undergoing fundamental changes due to the rapidly growing amount of wind energy conversation system, and concentrating on maintaining generation-load balance and disturbance rejection. The prominent feature of the linear active disturbance rejection control approach is that the total disturbance can be estimated and then eliminated in real time. And thus, it is a feasible solution to deal with the load frequency control issue. In this paper, the application of the linear active disturbance rejection control approach in the load frequency control issue for a complex power system with wind energy conversation system based on doubly fed induction generator is investigated.
